A pulley "i3 is suspended from the hang-l ere 2. 'The bolt 9 passe'sthrough'op e in s which are provided therefor int the ohannefmembers provided between fthe spar sections" fi'and the 3 hangers [2. The, other end of the sectionst are.

and advantages of the invention will becomeap parent from a study of the following specifica I tion, taken in connection with the accompanying drawings wherein like characters of '1 reference 7 designate corresponding parts throughout the several views, and wherein:

Figure 1 is a topplan view, showing a 'spar constructed, in accordance with thepresent invention erectedon a boat. Y

Figure 2 is a view in side elevation thereof. 7 Figure 3 is, a cross-sectional view through the 7 I i boat, taken substantially on the line agein -r ure 2, showing the spar in rear elevation. a

.Figure 4 isa vertical sectional view through the upper portion of the deviceftaken substantially on theline 4-4 of Figure 2. V r

Referring now to the drawingsin detail; it will I, be'seen that the embodiment of thetinvention which ha been illustrated comprises an inverted substantially U-shaped; frame of suitable wood. or other material, which is designated generally by the reference numeral l. Sockets 2 are provided' on the deck 3 of a power boat 4 adjacent. the forward end of the cabin 5 of said boat. The socket 2 are for the reception of the endportionsof the frame I.

The frame I includes a pair of duplicate, complemental, oppositely curved or bowed sections 6 to which forwardly and rearsubstantially The sections 6 ;are"thenlashed-to the sheers l.8'

One I end of the sections 6 are detachably connected bers, the adjacent end portions'ofthe sections; andrthe hangers for securing'said sectionsato-j gether, and a pulley suspended from the hangers.
